Abstract (en)

[origin: EP2770795A1] The present invention discloses a method, an apparatus, and a system for establishing a device-to-device connection, and relates to the field of communications technologies. The method includes: obtaining, by a device-to-device D2D server, registration information of a first device needing to perform D2D communication; performing pre-matching for the first device according to the registration information of the first device to find a second device; and triggering an evolved Node Base eNB to establish a D2D communication link between the first device and the second device. In the present invention, a D2D server triggers an eNB to establish a direct device-to-device connection between two devices, so that establishment and usage of the connection between the two devices can be controlled by a network. In this way, a carrier can implement control, management, charging, and the like of D2D, and it is ensured that interference of D2D on a common UE is under control.
